NOW Foods A 25.000 UI 250 Cápsulas blandas

What is Vitamin A?

Vitamin A is an essential fat-soluble nutrient that plays a crucial role in various bodily functions. It occurs in two main forms: retinol, found in animal sources such as fish liver oil, and provitamin A carotenoids like beta-carotene, present in vegetables. This NOW Foods supplement offers 25,000 IU of retinol derived from fish liver oil, a highly bioavailable form that the body can use directly.

Benefits of Vitamin A

According to the European Food Safety Authority (EFSA), Vitamin A contributes to several key physiological functions:

• Maintenance of normal vision: Vitamin A is an essential component of rhodopsin, a protein in the retina that allows for vision in low light.
• Normal functioning of the immune system: It helps maintain mucosal barriers and the activity of immune cells.
• Maintenance of normal skin and mucous membranes: It promotes cell renewal and tissue integrity.
• Normal iron metabolism: It participates in the mobilization of stored iron.

These benefits are supported by health claims authorized by the EFSA, ensuring that the information is accurate and reliable.

How much Vitamin A do I need?

The reference intake for adults in the European Union is 800 micrograms of retinol equivalents (RE) per day, which is approximately equivalent to 2,667 IU. However, this supplement provides 25,000 IU per capsule, a significantly higher dose. Therefore, it is important to note that the tolerable upper intake level for adults is 3,000 micrograms RE (10,000 IU) per day for retinol, although some individuals may require higher doses under professional supervision. Do not exceed the recommended daily dose indicated on the package. Consult a healthcare professional before taking high doses.

What is the difference between retinol and beta-carotene?

Retinol is the active form of Vitamin A found in animal-derived foods. It is directly absorbed and utilized by the body. Beta-carotene, on the other hand, is a precursor that the body converts into retinol as needed. Fish liver oil retinol is especially effective for those seeking a direct and potent source, while beta-carotene also acts as an antioxidant. This product contains pure retinol, ideal for specific supplementation.

Possible side effects and precautions

Excessive consumption of preformed Vitamin A (retinol) can lead to toxicity, with symptoms such as nausea, dizziness, dry skin, and, in the long term, liver damage. Pregnant women or those planning to become pregnant should not exceed 3,000 IU of retinol daily, as high doses can cause birth defects. This supplement contains 25,000 IU, so it is crucial not to take more than one capsule per day unless directed by a doctor. Keep out of reach of children. Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose.

How to choose the best Vitamin A supplement

When selecting a Vitamin A supplement, consider the following aspects:

• Form: Retinol is more potent and direct; beta-carotene is safer in high doses. This product uses fish liver oil retinol, a natural and effective source.
• Dosage: Adjust the dose to your needs. High doses like 25,000 IU should be used with caution and preferably under professional advice.
• Quality: NOW Foods is a brand recognized for its manufacturing standards, and this product is produced in registered facilities subject to quality controls.
• Format: Softgels are easy to swallow and facilitate absorption.

For most people, a balanced diet provides sufficient Vitamin A, but in cases of deficiency or specific needs, a supplement like this can be beneficial. Always consult a healthcare professional before starting any supplementation.

Natural sources of Vitamin A

In addition to supplements, Vitamin A is found in foods such as beef liver, fish liver oil, carrots, sweet potatoes, spinach, and eggs. Combining a varied diet with a high-quality supplement can help meet daily needs safely.
